This year he’s on target to sell more than 20m books in the US alone, adding to his $1.5bn in global sales, making him the world’s bestselling author by a mile.” But Patterson’s “scribbling” isn’t just a super-efficient brand, reaching for global dominance; it’s also a collaborative effort, honed and refined by a number of highly talented individuals.
